Reference is now made to FIG. 1A is a schematic representation of an example of a system for providing ground support to an aerial vehicle 200. The system includes an aerial vehicle 200 supported by a control server 300 and three portable ground stations 100A, 100B and 100C.

Each ground station 100 may be a self contained unit including an extendable landing pad 120 which, when open, may provide a platform for vertical takeoff and landing of an aerial vehicle such as a hovercopter, a quadcoptor, a rocket propelled vehicle, a multirotor drone or the like.

It is a particular feature of the ground station 100 that the extendable landing pad 120 is enabled to transition between at least two configurations, and open configuration and a closed configuration.

In the open configuration, as shown in the first ground station 100A, the landing pad extends beyond the borders of the casing of the ground station 100A such that the dimensions of its area are sufficient to allow the aerial vehicle 200 to land.

In the closed configuration, as shown in the other ground stations 100B, 100B, the landing pad is retracted such that it is contained within the protective casing of the ground station 100.

It is a further feature of the ground station 100 that a landed aerial vehicle may be withdrawn into the protective casing along with the retracting landing pad 120. Once within the ground station 100, a charging mechanism may be used to charge the onboard battery of the aerial vehicle.

Accordingly, by deploying multiple ground stations, the operating range of the aerial vehicle maybe increased as required.

It is further noted that multiple ground stations may support multiple aerial vehicles or a single ground station may support multiple aerial vehicles as required.

For example, a ground station containing an aerial vehicle, may open to allow the first aerial vehicle to take off and a second aerial vehicle to land before closing to charging the second aerial vehicle. In this way, continual operation of at least one aerial vehicle may be supported with potentially no down time.

It will be appreciated that where multiple ground stations are used, a network of aerial vehicles may similarly supported.

The control server 300 may be operable to coordinate the network of ground stations 100 and aerial vehicles 200. Accordingly, communication units 190A-C, 390, such as radio transmitters and receivers or wired communication lines, for example, may be provided on the controller as well as each ground station and each aerial vehicle to enable a communication channel between the control server 300 and each of these networked units as well as between the networked units themselves.

Referring now to FIG. 1B representing an aerial view of the ground stations represented in FIG. 1A, the ground units may include homing aids 142, 140 for guiding the aerial vehicle 200 towards the landing pad 120.

Various homing aids maybe used with the ground stations, such as a beacon or a visual indication.

Beacons may include, for example, infrared beacon signals, radio frequency beacon signals, visible light beacons LED beacon, a visual beacon, an audio beacon, an audio beacon, ultrasonic signal beacon or the like as well as combinations thereof

Additionally or alternatively, visual indications may be provided such as a pattern of contrasting dark and light areas readily identifiable from above.

In some systems, the aerial vehicle may be an autonomous vehicle having a payload including only a power pack and a camera. For example, in order to reduce load carried by the aerial vehicle it may be necessary for the aerial vehicle to operate without any on board communication units.

Accordingly, the camera maybe used as the homing aid detection mechanism. To this end a first visual indication 144 may be provided on the outer surface of a closed ground station, for example on the closable lid or top-closing. The first visual indication may include a first pattern of contrasting dark and light areas readily identifiable by the aerial vehicle from high altitude such that the aerial vehicle may be guided towards the ground station.

A second visual indication 142 may be revealed when the ground station is opened and the landing pad 120 is extended. The second visual indication may include a second pattern of contrasting dark and light areas configured to be identifiable from lower altitude and configured to guide the aerial vehicle towards the center or other desired point upon the extendable landing pad 120..

Reference is now made to FIGS. 2A and 2B which schematically represent example of a ground station for an aerial vehicle in its open configuration. FIG. 2A represents an isometric view and FIG. 2B represents a top view.

The ground station 100 includes an extendable landing pad 120 having a base platform 121, side extensions 122A-D and bridging lobes 123A-D.

The base platform 121 which may provide a platform for supporting and aerial vehicle 200, may be raised from within a protective casing 110. Accordingly, an elevator mechanism 130 may be provided to raise and lower the base platform.

When the base platform 121 is in the raised configuration an aerial vehicle 200 placed thereupon is no longer contained by the protective casing and has clear lines for takeoff at almost any angle. The side extensions 122A-D are configured to extend the area of the landing pad. The bridging lobes 123A-D are provided to fill the corner gaps formed between the open side extensions. The side extensions 122A-D and the bridging lobes 123A-D are all preferably configured to retract, perhaps by folding up such that they fit into the casing when closed.

For example, the side extensions may be variously configured to unfold from the base platform 121 or from the top of the protective casing 110 as required.

Typically, the base platform 121 is rectangular and four side flaps are rotatably coupled to each edge of the base platform and configured to fold out of the protective casing. Alternatively, other shaped base platforms and side extensions may be preferred such as the triangular example shown in FIGS. 6A-B, still other shapes and configurations will occur to those skilled in the art. For example, is still other embodiments, the side extensions may include wings operable to extend telescopically from an edge of the base platform or the top-closing as required.

Referring now to FIGS. 3A and 3B which schematically represent an isometric projection FIG. 3A and a cross sectional view FIG. 3B of the example of the ground station 100 in its closed configuration.

The base platform 121 has been lowered by the elevator mechanism 130 into a recessed configuration such that the side extensions 122A-D, bridging lobes 123A-D and supported aerial vehicle 200 are all contained within the protective casing 110.

The protective casing 110 includes a bottom-panel 116, four side-panels 112A-D and a top-closing 112. The top-closing 112 comprises a first outwardly folding flap 112A rotatably coupled along a common edge with a first side-panel 112D, and a second outwardly folding flap 112B rotatably coupled along a common edge with a second side-panel 112B opposite to said first side-panel.

Where required, the side-panels may serve as windbreakers configured to reduce crosswinds across the extendable landing pad during takeoff or landing.

It is noted that with the base platform in the recessed configuration, the side extensions 122A-D and the bridging lobes 123A-D are all folded into the casing and contained therewithin.

The protective casing 110 is preferably constructed from a material transparent to radio signals such that an aerial vehicle contained within may receive satellite navigation signals or the like. Accordingly, in some embodiments non conducting materials are used to form the casing in order to avoid the construction of a Faraday cage which would block any electromagnetic radiation from penetrating.

Referring particularly to FIG. 3B, a possible charging mechanism 150 is shown for charging the contained aerial vehicle 200. A power supply 151 such as an electrochemical cell or battery, a fuel cell or the like, is operable to maintain a potential difference between a first conducting terminal 152B, 152D and a second conducting terminal 154. One conducting terminal may serve as a charging anode and the second conducting terminal may serve as the charging cathode.

For illustrative purposes only, in some embodiments, the first conducting terminal 154 may comprises conducting elements embedded in the base platform 141, perhaps in strips, such that they conductively couple with a corresponding conducting element 254 in the foot of the aerial vehicle placed thereupon. The second conducting element 152B, 152D may be embedded in a side flap 122B, 122D of the landing pad, such that when folded up it may conductively couple with a corresponding conducting element 252B, 252D on a propeller tip of the aerial vehicle 200 housed within the protective case.

In other embodiments, conducting elements may be incorporated into other sections as required, for example, within the walls of the protective casing or the upper closing such that they conductively connect with other parts of the aerial vehicle.

Optionally the ground station 100 may include power generators such as photovoltaic panels, wind turbines or the like which may be used to charge its integrated power supply. Alternatively or additionally, the ground station may be connected to the power mains. Where Required, the photovoltaic panels may be integrated into the top closing of the protective casing for example as part of the visual indication of a homing aid.

Referring now to FIGS. 4A-E, showing a series of cross sections indicating how the example of the ground station 100 may transition between an open and a closed configuration.

In the base platform 120 is in its recessed configuration as shown in FIG. 4A, the side flaps are folded upwards such that they run along the side walls and are contained within container below the top closing 112A, 112B.

The elevating mechanism 130 may drive the base platform such that it is raised or lowered as required. When raised the side extensions may urge open the top closing and the side flaps fold out.

It is further noted that an aerial vehicle landing off center of the landing pad as shown in FIG. 4E, may be forced back into a center position by the closing side flaps such that it is centered onto the base platform 121. Other centering mechanisms such as articulated side arms or the like, will occur to those skilled in the art.

Referring now to FIGS. 5A-C showing a series of isometric projections indicating how another example of the ground station may transition between an open and a closed configuration by sliding two side doors 5112A, 5112B of the top-closing such that the landing pad 5120 may be raised.

Referring now to FIGS. 6A and 6B, still another embodiment is shown in which a triangular ground station 6120 is presented in which the top closing is formed from three side panels 6122A-C which unfold to both open the container as well as to form the extended landing pad 6120.
